Magnetorheological liquids, a process for producing them, their use and a process for producing polymer-coated magnetisable particles used in the magnetorheological liquids.
摘要:
Monodisperse crosslinked polymers prepared by seed/feed polymerization have less tendency to tack when a microencapsulated monodisperse crosslinked polymer has been used as seed. Compared with the seed used, the seed/feed polymer obtained exhibits substantially less broadening of the particle size distribution when microencapsulated seed has been used.
